Web Performance Improvements can be Beautiful too!

Crate and Barrel joins The Home Depot and Le Monde in the elite group of companies that is actively working on improving web performance, to provide better end user experience and ultimately, improve their bottom line.

This past week, I received another call from the Crate and Barrel team. “Hey Mehdi, we have been working on our performance and wanted to get your feedback!” I was shocked by the changes they had implemented. As I was charting their data for the last 6 months the first word that came to mind was “Beautiful”.

After the close of the holiday season, the Business and IT team at Crate and Barrel decided to make web performance a key priority for 2012 and I believe they are going to do very well this year.

Without any further interruptions here are the results:

The time to Document Complete (or onload) improved by more than 49%

The Total Page Load time improved by more than 39%

Here are performance measurements before and after the “Perflift” from 10 US nodes since Nov 2011.

I picked a few dates to highlight the improvements:

Document Complete and Web Page Response

From a WPO (Web Performance Optimization) perspective the engineering team did a fantastic job at:

Combining images with CSS sprites

Reducing the number of third party tags, and loading the tags after document complete.

Adding proper expiration headers to assets

Relying on “Text” in place of images when possible

Minification of JS and CSS files

The total downloaded bytes was cut in half:

I hear that the team is not done yet! I look forward to Crate and Barrel ranking very high in 2012 Shopping Season.

Congratulations to the entire Crate and Barrel Team for pulling off this “Perflift” (think Facelift, a rejuvenating SPA for website) successfully! Companies from around the world should take a close look and learn from Crate and Barrel, Le Monde and The Home Depot.
